As noted earlier, CM Punk joked about TNA being an indy league during a panel Q&A at Comic-Con in Chicago this past weekend.

Kurt Angle took offense to Punk's comments, and wrote on his Twitter last night, "Punk wants to Say Tna Is An Indy League? I Was On top in Wwe when You Were trying to Get a Job Anywhere. It Was My Choice to go to Tna. ... If I ever See You Punk, Hide b---h!"

Angle issued an apology for his comments on Twitter tonight, writing, "I apologize to Tna and Wwe fans for My Comment. I don't expect Punk to apologize to Tna. But I'm sorry.respect4thebiz."

He later clarified that he was apologizing to the WWE and TNA fans, and not to Punk.
